To allyulwm 'it mayl concern:

'Be it known that I, lGannon L. LYON, a

` citizen of the United States, residing at Nahant, in the count of Essex and Commonwealth of Massac usetts, lhave invented a new and useful Improvement Iin Crank- Boxes of Gasolene-Engines, of which the following is a specification.`

M f invention relates to improvements in cran boxes of gasolene engines whichrequire a crank box compression, and the objects of iny invention are first to improve the compression and to Vstop the leakage of gases ,from the crank chamber, second to iinprove the lubrication ofthe bearings. It is -well known that in all engines which use the crank chamber compression, the bearings become worn to the extent that the gases blowr out of the case arouiid the 'crank shaft, and also through the joint .made by the crank shaft bearingmnd crank case. This i not only affects the compression, but also'he lubrication, blowlngthe latter out and cutting it with the gasolene mixture. The more the bearing 1s worn, the greater the leakageand loss of'fnel. My device overcomes all crank case leakage `around tl'ieshaft and bearing joints.

` l attain the objectsof my invention as shown in the whicln--LA p Figure 1 shows a section of a crank case,

'accompanying drawings in shaft. and bearings of a gasolene engine.

i?. shows a section of a crank Vcase with a onble protection of the compression.

Referring in detail to the drawings, 'and l irst to Fig. thereof: A represents aci-ankshaft. B'rcpresents a cylindrical'bronze or Babbitt bearing, in which said shaft turns, and which 1s provided, at cach end, with an annular flange C. H represents a crankcasing, which is providedytoward each end, withv an annular reccssh, in which itswthe iianges C. The upper portion of the cylindrical crank-casing is provided with `a cy-A lindrical extension il?, which projects beyondthe outer end ot the cylindrical bearing B, and is internally screw-threaded, as shown at F. The regi-on between the-extension h? andthendjacent portion of the crank-sliaft A therefore forms a socket or chamber f. In

l the bottoni` of this socket and disposed against the endof the annular flange C of the bearing B, and .cncircln the crankshaft A, is a iexible packing, preferably formed with a 4conical or tapering upper surface fl, as shown.' Encirclmg the upper4 cap E, cnrryinga de `ending c lindric'al follower e, also encirdiing said 5haft A; which follower is extcriorly threaded, as shown at- F- to engage' the internal threads l" of the extension'h2 of the casing H, and has, preferably, a' dished-out bottom e to register and engage with. the conical or tapering upper surface d of Athepacking D. When the ring lower e engaging the extension'hg and said follower fully screwed down, thesockct or chamber f will be closed and. filled by said followeraud the packin D compressed, the wedging action being en anced by the tapering contour el of the upper portion of the packing D and the corres iondingly inclined bottom surface c' of the ollowcrc.

Referring, now, to fication of niy invention: the outer end of the extension 11,2 of the casing H is provided with screw-sockets z', iwith which engage screws (not shown) extending through slots the ring'niay be locked against the .casing H. In this form of device, also, there is an arrangement of double packing; that is to say,.in addition to the annular packing in the socket or chamber g, there is provided an additional packing J disposed in the and the ,shaft ik, which packing, when the ringil is brought against the outer ond of the casing Il, willA inipingc against the outer end of the bcarino B, as is obvious. Y Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is: l

' Tho-combination with a shaft, oiE a cylindrical bearing encircling the saine, of a cylindrical casing encircling the bearing and provided threaded extension projecting beyond t e outer-'end of said bearin said extensionv and thc shaft-informing there ictwe'en va socket, a

portion ot' the crank-shaft A is av ring or- Fig. 2, showing a modi socket. or chamber between the follower e2' E is adjusted with the fol- Y vI lin the rim of the cap or ring E, whereby with a cylindrical, internal] f1-tying :L depending, exteriorlythreaded "i @ESGE-"UE i" packing.
